whose dimensions are 2 m, 1.5 m and 80 cm. Find the
cost of wood used to make it at the rate of ₹120.55 per m²
​

Answer 1

Answer:

length = 2m = 200cm

breadth = 1.5m =150cm

height = 80cm

TSA= 2*(lb+bh+hl)

=2[(200*150)+(150*80)+(200*80)]

=2[30000+12000+16000]

=2*58000

=116000cm²

in meters = 1160m²

cost of wood per m² = 120.55 rs.

cost of wood for 1160m² = 120.55*1160

=139838 rs. answer
